GAS-BURNER.

Specification of Letters Patent.

Application filed June 21, 1904. I $eria1 No. 213,451.

To all whom, it may concern:

My invention relates to improvements in gas-burners, and more particularly to heat-- ing-burners adapted for use in instantaneous water-heaters of the character shown in Patent No. 759,607 to myself and James Gr. Hallas and dated May 10, 1904:; and itsobject is to provide a device that can be constructed at small expense, with but little machinery and readily assembled and to provide the device with various new and useful features hereinafter more fully described, and particularly pointed out in the claims, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of a device embodying my invention, taken on the line 1 1 of Fig. 2; Fig. 2, a plan view of the same;

attaching a gas-pipe, as at 5.

Fig. 3, a detail in section at right angles to Fig. 1, taken on the line 3 3 of Figs. 1 and 2; Fig. 4;, a detail of a portion of the gas-ring and water-tube; Fig. 5, an end view of one of the lugs to support the gas-ring, andFig. 6 a detail of one of the gas-nipples.

Like numerals refer to like parts in all of the figures.

1 represents a hollow ring to distribute gas to the various nipples and having means for This ring is provided with a radial passage 2 to admit water to a stand-pipe in the axisof the same and cast integral therewith. The ring isalso provided with radial lugs 3, provided with recesses 4, whereby bolts can be inserted to support the ring in place within thecase of the water-heater. In the upper side of the ring are a series of openings 7, surrounded by packing-grooves 8, which-in turn are surround by suitable bosses 6, within which latter are inserted the lower ends of the mixing- .tubes 9, beneath each of which is inserted the flange 20 of an upwardly-projecting nipple 11, through which nipple the gas is discharged into the axis of the mixing-tube. Any suitable packing is inserted in the groove 8 to Pate ntecl sept. 26, 1905.

prevent escape of gas. lOrepresents lateral openings in said tube to admit air, which becoming mixed with gas in the tube 9 is discharged into an annular chamber 18 in the burner-head of substantially the sameradiusas the gas ringl This head is providedwith' openings opposite each mixing-tube and bosses 13 on its under side to surround'and' radially therefrom is divided horizontally, as

at 23 and 24, and 'the lower part in its radial extension is provided with upwardly-projecting tubes 14, through which air is supplied to the interior of the flames. The upper part 15 is provided with a corresponding series of upwardly-projecting tubes 16 of larger interior diameter than the outside of the tubes 14 and arranged concentric therewith, and these tubes 1 k and 16 are so constructed at their upper ends that they present concentric parallel surfaces in closeproximity to each other, leaving "a narrow annular slit 17 therebetween and of suflicient vertical extent to prevent the fire from passing downward therethrough.

In this device the gas-ring, the nipples, mixing-tubes, and portions 12 and 15 of the head areassembled as shown in the drawings,

and are secured in place bybolts 19, which extend through lugs 21, projecting inward on the respective ringl and upper plate 15, thus securely :holding all the parts together by bolts that are easily and quickly removed or inserted, as occasion may require. Theouter edges of the parts 12 and 15 are further secured to each other by means of suitable bolts 22 inserted therein. All of the openings for these bolts '19 and 22 can bemolded in the castings without necessity for drilling of the same. Thus the only: machining required is to tap the water-passage 2 and the pipe connection 5 and to manufacture the'flanged nipples. The gas-ring and chamber 18 are of much less radius than the circle of burners, and thus require lessmaterial than if below the burners. 'The mixing-tubes being at one side of instead of beneath the burners and the flow from the chamber 18 to the'burners being radial instead of vertical secures more equal distribution of the mixture to the burners. 1 am thus able to produce a very satisfactory burner-"at a very small cost and at the same time one that is easily kept in order or repaired.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is

1. As an article of manufacture a gas-burner comprising a gas-ring and an annular distributing-chamber of substantially equal radius, mixing-tubes connecting the ring and chamber, a radial extension on said chamber and concentric burner-tubes on said extension.

2. As an article of manufacture a gas-bu rner comprising a gas-ring having top openings surrounded by packing-grooves and bosses, a burner-head formed of two separable plates, and having an annular chamber of the same radius as the gas-ring, openings and bosses in the lower plate, mixing-tubes and flanged nipples between the gas-ring and head, radial extensions of said. plates, inner tubes in the extension of the loWer plate outer tubes in the extension of the upper plate, lugs on the upper plate and gas-ring, and bolts connecting the lugs.

3. As an article of manufacture, a gas-burner for Water-heaters, comprising a gas-ring, radial lugs on the ring and having recesses lor bolts, a radial water-pipe in said ring, top openings in said ring, packing-grooves and bosses surrounding said openings, flanged nipples above said openings, mixing-tubes above the nipples, a bottom plate having openings and bosses to receive the mixing-tubes, upwardly-extended air-tubes in the radial extensions of the said plate, a top plate, also radially extended and having tubes surrounding the air-tubes and spaced apart therefron'i, lugs on the top plate and gas-ring, and bolts connecting the lugs.

In testimony whereof I afiix my signature in presence of two Witnesses.
